PHPStan failed using Translatable

[Ciloe]

I there,

I'm using translatable from Knp and I have this error :

#40 {main}

I have this in my composer.json :

...
"config": {
        "bin-dir": "bin",
        "preferred-install": {
            "*": "dist"
        },
        "sort-packages": true,
        "allow-plugins": {
            "phpstan/extension-installer": true,
            "symfony/flex": true,
            "symfony/runtime": true
        }
    },

So the file vendor/knplabs/doctrine-behaviors/phpstan-extension.neon is already included (related to #516

How can I fix it ?

Hi ! I have more informations :

I have this line : $this->entity->translate($locale)->$fieldName ?? ''; and $entity is declared with two interfaces : protected TranslatableInterface&ExposeTranslatableFieldsInterface $entity,. So when StaticTranslationTypeHelper::getTranslationClass is used, you will get the first reference class : $translatableClass = $type->getReferencedClasses()[0];. Unfortunately, the class ExposeTranslatableFieldsInterface is the first in the array...

I can code the correction. Maybe, a foreach ? I will try this.

It's still broken today, took us some time to find out why we suddenly got a crash after adding phpstan/extension-installer until we noticed this library has its own extension integrated. Shouldn't it be a separate library anyway?

I tried to fix, but my change will move some functionalities. I don't know if this will pass... It's not a simple change, but I don't know the project so...
